Many Crassulaceae are grown for ornament, especially Sedums upon rockeries, 

 and the Rose-root or Rhodiola rosea, (E. B. viii. 508.) a plant with numerous 

 succulent stems, six inches high, thickly clothed with flat, oval, glaucous leaves; 

 and the flowers, which are minute and yellowish green, in dense terminal corymbs. 

 The root, when freshly cut, exhales an odour resembhng that of the monthly 

 rose. The Cobweb House-leek or Sempervivum arachnoideum has rosettes like 

 those of the S. tectorum, but smaller, and with white fibres crossing backwards 

 and forwards from leaf to leaf, as if a spider had spun its web among them. In 

 green-houses the splendid Crussula coccinea is the most beautiful and frequent 

 representative of the family, though emulated by many Sedums, Sempervivums, 

 and Echeverias, crimson, scarlet, and yellow.
